Leaving your car exposed to the elements? It's doing more damage than you think. The harm is gradual, but it's real. And expensive. Instead of spendy body work and repair, why not try the low one-time cost of the PolyPro 1 Car Cover? Its water-repellent / breathable single layer fabric shields against rain, sleet and snow while also preventing mold and mildew from building up under the Cover.
